The use of radiofrequency (RF) for selective electro-thermolysis has been found to produce a highly efficient heat effect on biological tissue. Different from optical energy, RF energy is dependent on the electrical properties of the tissue and not on the concentration of chromophores in the skin for selective heat destruction of targeted sites. The epidermis is spared by applying a cooling spray which protects it from the heating effect of the device. The dermis is then heated uniformly and volumetrically, sparing the epidermis. Partial collagen denaturation occurs as a result of this heating, which leads to collagen contraction and thickening. Some shrinkage of the collagen framework may occur immediately due to the fibril denaturation. More tightening follows due to a natural inflammatory wound healing response that triggers new collagen formation and further skin contraction.
